Merge tag 'renesas-soc-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc

From Simon Horman:
Renesas ARM-based SoC updates for v3.11

* Increased clock coverage for r8a7740, r8a73a4, r8a7778 and r8a7790
* Use fixed clock ratio for r8a7778
* Always use shmobile_setup_delay for sh73a0
* Add add CPUFreq support for sh73a0
* Check kick bit before changing rate on sh73a0
* Do not overwrite all div4 clock operations on sh73a0

* Cleanup SH_FIXED_RATIO_CLK and SH_FIXED_RATIO_CLK macros
* sh73a0: Use DEFINE_RES_MEM*() everywhere
* r8a7740: Make private clock arrays static
* r8a7778: Correct model number

The last four changes listed above are cleanups. I have included them
in this series as all bar the last one are dependencies of non-cleanup
patches.
